How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security100
- No malware found by supply-chain analysis.Pass
- A known CVE affects couchbase, but no fixed version has been published, so there is nothing to upgrade to. View diagnostics → Partial
- Runs hatchling.build at install time, a recognised build step with no custom scripting around it. View diagnostics → Pass
- 1 of 18 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency71

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

list_indexes ~205
List indexes in the cluster with optional filtering by bucket, scope, collection, and index name.

Each result contains: name, definition (CREATE INDEX statement), status, isPrimary, bucket, scope, collection, lastScanTime. If a required field is missing, the entry contains warning and raw_index_stats instead. Source depends on cluster version: v8+ queries ``system:indexes`` via the query service (RBAC-scoped — the connected user sees only indexes on keyspaces they can access); older clusters fall back to the admin-level Index Service REST API ``/getIndexStatus``.

run_sql_plus_plus_query ~121
Run a SQL++ query on a scope and return the results as a list of JSON objects. The query will be run on the specified scope in the specified bucket. The query should use collection names directly without bucket/scope prefixes, as the scope context is automatically set. Example: query = "SELECT * FROM users WHERE age > 18" # Incorrect: "SELECT * FROM bucket.scope.users WHERE age > 18"
| Name | Type | Req | Description |

If bucket name is not provided, it will not try to connect to the bucket specified in the MCP server settings. Returns connection status and basic cluster information.
| Name | Type | Req | Description |
|---|---|---|---|
| bucket_name | – | – | – |
Structured output declared, but exposes no named fields.
